Application filed October 217 19115.

Serial No. @6,49% w lowing :i specification.

This invention relates in general to our trucks, und of special utility in connection with truckS oit' the :tour-wheeled type, wherein the brakes are forced upon the trend of' euch of the four Wheel?1 sinlultsrneously from both sides of the transverse center oit the truck.

The primary object of this invention is to rovide nn ini Jroved brake benin su i ortinol h spring which is adapted to be held rigidly in pince against longitudinal or transverse movenxent, While nt the sinne time possess.- iig the adequate lzieilitiege ALor its ensy removil und replacement which greatly facil; itute the building ot trucks well :is inakingl repairs to the some.

`With these and other objects in view which will more readily nppezir as the nnture of the invention is better understood, Athe saine consists in the novel construction, oomloination und nr alignment of parte hereinnt'ler more fully described, illustrated und claimed.

It will.y of course, loe understood that the invention is susceptiliile to structural modifications without depurtlng from the spirit or scope ol the invention,1 but u preferred and pruetirnl embodiment of the sinne is. shown in the accompanying drawings, in Which-- i Figure 1 n partial pllnl view showing; o, Our-Wlieeled enr truck embodying the present invention.

The nid sufepeneion Springl clump l-l is preferably positioned on the longriliulinul renter line of the trunk in direct nlinement with the rouler ol the hrnke henin und the suspeneion springt.

ln view of the or igfoi1igl deseriplion of the various essentiel strneturil details of the present invention, it will quito readily he seen that the Suspension sp1-ingr clump 14,

Patent ed fitug. Iilfil et y License isiletaehably fitted to the underside oit the transverse angle tie bars 13a, by means of suitable fasteners which cooperate with the attaching [langes 1G, and' that the suspension spring 10 is placed in the channel 15 so that it extends longitudinally of the truck proper.

The concave portion 12 of the suspension spring l0 bears against the surface-18 of the channel 15, which is an integral part of the suspension spring clamp, and that the said suspension spring 10 is detacliably held to said suspension spring clamp 14 by means of the bolts E21 Which pass through the alined bolt receiving openings 2O in the Walls 1-'9 of the channel and engage the suspension spring at the junction 19B, of the concave portion 12 With the body 11, thus effectively locking the suspension spring to the suspension .spring clamp so as toy prevent longitudinal movement or creeping1 in the channel.

1t is believed to be apparent from the foregoing .description and accompanying Q drawings that I have made a decided improreinent in brake beam suspension devices, inasmuch as by employing' a snspension spring in the manner explainedtlie atta ,lnuent and detachment is readily accomplished, and further when properly pnt in place the device not only supports the brake beam at its proper angle with reference to the transverse center line' of the truck Wheels, but also possesses the required eleniente of rigidity and'stability which are so essential to modern railway trucks.

1. In a car truck the combination With a truck traine, transverse tie bars, brake beams and brake beam supporting shoes, of a suspension spring arranged longitudinally of the truck naring a central concave portion and also having free inclined end portions, and detachable means for rigidly clamping the central concave portion of the spring; to the truck.

2. In a car truck the combination with the truclz traine, transverse tie bars, brake beanis and brake beain supporting shoes, of a suspension spring arranged longitudinally of the truck and havingp a central concave portion and oppositely disposed free inclined end portions, said inclined end portions being; unconnected with, but in bearing contact with said brake beani sul'lportingg slices, and detachable nieans tor rigidly clamping the central portion oi the spring to the truck.

8, ln a ear truck the combination with the truck traine, transverse ytie bars, brake beams and brake beam supporting' shoes, of a clainp detaehably fitted to said transverse angle tie bars, a suspension spring having a concave portion adapted to be engaged by the clamp, and means for drawing the spring` and clamp together to prevent longitudinal inoveinent of the suspension spring.

ll. ,ln a car truck, the combination with the trnclr traine and brake beam, of a clan'lp having a suspension spring receiving chan.- nel adapted to be fitted to the transverse tie bars ot the truc-k, a suspension spring` ar ranged longitudinally of the truck and lying;1 Within the channel of the clamp, and a plurality of bolts which are adapted to bind the springto the clamp so as to prevent lon gitudinal movement.

.ln a car truck, the combination with the frame and brake rigging' of clamp llaving a central channeled portion, the bottoni of which presents a convened suspension spring' bearing surtace. and the depending spaced apart side -walls of which are provided with oppositely located alincd openings, attaching l'langes eXtending 'laterally `l'roin the channeled portion, a suspension springI arranged longitudinally of the 'trncli' and adapted to lie Within and be clarinY l in position within the channeled portion of the binder, andlnieans tor entering' the openinos in the Walls ot' the channel to detachably lock ythe suspension spring to the ilanip.
